Add support for ARM v5t, v5te architectures and Intel's XScale extensions


Hi Guys,

  I am checking in a patch to add support in binutils for ARM's v5t,
  and v5te architectures, and Intel's XScale extensions to the v5te
  architecture.

  In order to be able to compile a toolchain actually targeted at the
  xscale it is necessary to apply a patch to the top level config.sub
  file, which I will be submitting separately.  In addition this patch
  does not contain updates for GDB, GCC or the simulator.  I hope to
  submit these at some point in the future.

  I have only included the ChangeLog entries below, since the patches
  themselves are rather large.

Cheers
	Nick
